Características da carcaça e carne de biotipos de ovinos localmente adaptados agrupados com base na morfologia corporal

Abstract

Objective of study through systematic literature review the characteristics of carcass and meat of sheep and verify that these evaluations have correlation with race or phenotypic variability (Chapter I). Through exploratory study aimed to also identify different biotypes of lambs Pantanal and find out the effects between the carcass characteristics and meat quality (chemical and instrumental parameters), (Chapter II). The chapter I was based on a meta-analysis, in which a search for scientific articles in the public domain, which resulted in database composed of 52 scientific papers, 182 treatments, 1893 animal and 137 variables with established work between 2010 and 2018, totaling 8 years of research. The data exhibit great variability, which reinforces the importance of the study that involves mainly phenotypic variability when it seeks to standardize a native race, diversity and physiological responses explain this variability. Chapter II were used 34 lambs of the flock of sheep he Pantanal with an average age of 82 ± 8.6 days, males, weaned, no neutered, with average body weight 12.8 ± 3.5 kg initial, grouped from cluster study for identification of biotopes through your body morphology. The slaughter of lambs was set by using body weight (28-30 kg) and body condition score (minimum 2.75). The differentiations of biotypes were observed for three different situations: quantitative morphology end, qualitative and quantitative morphology morphology final + qualitative morphology. The study was explored in statistical analysis on Multivariate form (factorial and cluster) and univariate (analysis of variance and averages) in order to explore as much as possible the diversity of the grouping. The groups showed little distinction, however desirable characteristics when it comes to meat quality.
